Tranquillity Base > mChapters

mChapters is a simple, intuitively and easy-to-use chapter marker editor for MP4/MOV files. Chapter markers will make it easy for users to skip a playing-time to a specific time. It's very useful especially in long duration videos and audios.

mChapters saves chapter marker times and titles as a text track into a file. The text track format is defined by the QuickTime/MP4 specification.
In Macs, you can use chapter markers in QuickTime Player, iTunes and other apps that supports text track of chapter marker.
In iOS devices, TV app or Videos app supports chapter marker. But Music app does not.

mChapters does not re-encode audio/video data when saving. That does not affect the qualities, and that makes completing a quick save.

• Adding chapter markers by specified interval, number of divisions
• Adding chapter markers by importing text file
• Exporting chapter marker list as plain text (.txt)

macOS 10.12 or later

• QuickTime Movie (mov)
• MP4 file (mp4, m4v, m4a)

mChapters cannot open files which require any conversion or codec components in QuickTime Player. Or nothing will be displayed.

Please backup your data before using this app.
